Detail

This report used data from telemetry studies and fish counters to develop a statistical model to assess the potential impact of abstractions and water resource schemes on adult salmon entering freshwater.

The model quantifies the impact in terms of delay and mortality at tidal limit as well as the level of uncertainty. The results from the model simulations could be used in the decision making process to evaluate the impact of an altered flow regime on the number of salmon available to the fishery and for spawning.
